Starts generating a custom design system from a description of the product and its look, and returns the project id and project URL at once. Generation runs in the background and typically takes 1 to 3 minutes. get-design-system-status reports progress and returns the install command when it finishes. `baseDesignSystemId` starts from a catalog system the user picked, `userConfirmedCustom` records that the user chose fully custom, and `brandCss` builds from an existing brand token sheet, such as the output of extract-design-system. With none of the three, it generates nothing and returns the top catalog matches to show the user. Each call uses one credit from the user's Better Design account. Anyone with the registry or preview URL can view the generated source and previews.
